Question juridique clé
Was the pension fund liable to pay disability benefits under BVG?
Solution extraite
The case could not yet be decided on the merits because the decisive question was when the relevant incapacity for work began; the matter had to be remitted for further medical findings.
Motifs extraits
The existing medical file was insufficient. The Supreme Court found that work evaluations during employment spoke against an obvious pre-existing incapacity, while the lower court had inferred earlier incapacity mainly from prior short employments. A psychiatric expert opinion was necessary to clarify the onset of incapacity and the required temporal and factual link to later invalidity.
